The Complete Guttering Buyer's Guide 2025

Why Guttering is Essential

Guttering, also known as eavestroughing or a roof drainage system, is a crucial component of any home's exterior. Its primary function is to collect and divert rainwater away from your property's foundation, walls, and roof. A properly installed and maintained guttering system prevents a wide range of problems, including:

• Structural Damage: By channelling water away from the foundation, guttering helps prevent soil erosion and foundation cracks, which can compromise the structural integrity of your home.
• Damp and Mould: Without effective drainage, water can saturate the ground around your house, leading to dampness in the walls and basement, which in turn can cause mould growth and associated health issues.
• Roof Damage: Guttering prevents water from pooling on the roof, which can lead to rot, leaks, and damage to the roofing material.
• Exterior Damage: It protects your home's siding, paintwork, and landscaping from being damaged by cascading water.

Investing in a quality guttering system is a wise decision that will protect your home and save you from costly repairs in the long run.

Choosing the Right Guttering Material

uPVC

• Pros: uPVC is the most popular choice for guttering in the UK due to its affordability, low maintenance requirements, and ease of installation. It is lightweight, resistant to rust and corrosion, and available in a variety of colours to match your home's exterior.
• Cons: uPVC can become brittle over time and may crack under extreme weather conditions. The colour can also fade with prolonged exposure to sunlight.

Aluminium

• Pros: Aluminium is a lightweight, durable, and rust-proof material. It is available in a seamless form, which is custom-made to the exact measurements of your home, reducing the risk of leaks. It also comes in a wide range of colours.
• Cons: Aluminium can be more expensive than uPVC and can be dented by ladders or heavy impacts.

Cast Iron

• Pros: Cast iron is an extremely durable and long-lasting material that can last for over 50 years with proper maintenance. It has a traditional and aesthetically pleasing appearance, making it ideal for period or listed properties.
• Cons: Cast iron is the most expensive option and requires regular maintenance, including painting, to prevent rust. It is also very heavy and requires professional installation.

Copper

• Pros: Copper is a high-end, extremely durable, and long-lasting material that will not rust or corrode. It develops a beautiful patina over time, which adds to its aesthetic appeal.
• Cons: Copper is a very expensive material and requires specialist installation.

Guttering Profiles and Shapes

• Half-Round: This is the most traditional and widely used guttering profile. Its simple, semi-circular shape is effective at carrying water and is easy to clean.
• Square: Square gutters have a more modern and angular appearance. They have a higher capacity than half-round gutters of the same width, making them suitable for areas with heavy rainfall.
• Ogee: Ogee gutters have a decorative, S-shaped profile that is often seen on older, more traditional properties. They also have a high capacity and are a popular choice for their aesthetic appeal.

Key Considerations Before You Buy

• Rainfall Intensity: The amount of rainfall your area receives will determine the size and capacity of the guttering you need. For areas with heavy rainfall, you will need larger gutters and downpipes to handle the volume of water.
• Roof Size and Pitch: The size and pitch (steepness) of your roof will also affect the amount of water that needs to be collected. A larger or steeper roof will require a higher-capacity guttering system.
• Aesthetics: The style and colour of your guttering should complement the architectural style of your home. Consider the colour of your roof, windows, and doors when choosing your guttering.
• Maintenance: Consider how much time and effort you are willing to put into maintaining your guttering. uPVC and aluminium are low-maintenance options, while cast iron requires more upkeep.
• Budget: The cost of guttering can vary significantly depending on the material and style you choose. It is important to set a budget before you start shopping and to get quotes from several different suppliers.

Navigating the Buying Process

Choosing the right guttering system is only half the battle; finding a competent and trustworthy installer is just as crucial for a successful outcome. This section will guide you through the process of getting quotes and selecting the best professional for the job.

Step-by-Step Guide

• 1. Initial Research: Begin by identifying local guttering specialists. Use online directories, search engines, and local community groups. Don't underestimate the value of personal recommendations from neighbours, friends, or family. Create a shortlist of 3–5 reputable companies.
• 2. Request Detailed Quotes: Contact the companies on your shortlist and request a formal, written quote. Avoid accepting quotes given over the phone without a site visit. An installer needs to see your property to assess the roofline, measure accurately, and identify any potential issues. Aim to get at least three quotes to compare.
• 3. Compare Quotes Carefully: When you receive the quotes, don't just look at the final price. A professional quote should be itemised and clearly detail the full scope of work, including materials, labour, waste disposal, and VAT.
• 4. Check Credentials and Reputation: Before making a final decision, do your due diligence. Look for online reviews on trusted platforms, check if they are members of a recognised trade body (like the NFRC), and don't hesitate to ask for references from previous customers.
• 5. Agree on the Contract: Once you have chosen an installer, ensure you receive a formal contract or a written agreement that outlines the full scope of work, the total cost, payment terms, and the estimated start and completion dates.

Key Questions to Ask Your Installer

• About the Company & Insurance:
  • "How long have you been trading?"
  • "Can you provide proof of your Public Liability Insurance? What level of cover do you have?"
• About the Work & Materials:
  • "What is the warranty period for your workmanship and the manufacturer's guarantee on the materials?"
  • "What will happen if you discover rotten fascia or soffit boards? How will you handle this, and what are the potential costs?"
  • "How long do you expect the installation to take and how will you dispose of the waste?"
• About the Cost:
  • "Is the quote a fixed price, or could there be additional costs?"
  • "What are your payment terms? Do you require a deposit?"

The Importance of Professional Installation

While it may be tempting to install your guttering yourself, it is always best to hire a professional. A professional installer will have the experience and expertise to ensure that your guttering is installed correctly and will function effectively for years to come. They will ensure the correct 'fall' is created so water flows towards the downpipes, and that all joints are properly sealed to prevent leaks.
